Seven Republican state senators blocked a congressional map that would have handed the GOP two more House seats.
Last night, Indiana voters went Bobby Knight on them.
They fired six of them anyway – in a state Trump won by 20 points.
The Map That Would Have Changed Everything
Here is what those senators killed.
Indiana has nine congressional seats. Republicans hold seven. Democrats – in one of the reddest states in America – hold two.
Trump wanted that fixed.
His team drew a new map giving Republicans all nine seats. The Indiana House passed it 57-41 in December. Then it went to the Senate – where 21 Republicans joined every Democrat to kill it 31-19.
The House majority was not the problem. The Republican supermajority was not the problem. The math was not the problem.
A group of senators decided they knew better than Trump, better than the base, and better than the voters who handed them those seats.
They were wrong.
What Happened Tuesday Night
Trump endorsed challengers against seven of those senators.
Jim Banks and Turning Point Action poured $13.5 million into the races – up from roughly $250,000 spent on all Indiana Senate primaries two years ago combined.
The results were not close.
Travis Holdman of Markle – gone. Jim Buck of Kokomo – gone. Linda Rogers of Granger – gone. Dan Dernulc of Highland – gone. Greg Walker of Columbus – gone. Rick Niemeyer of Lowell – gone.
Every Trump-backed challenger who faced an incumbent won with at least 56% of the vote.
Walker had served 20 years in the chamber. He actually cried on the Senate floor in December arguing that giving Indiana Republicans all nine congressional seats would somehow destroy the party.
Last night, his district told him what they thought of that argument.
Only one senator who blocked redistricting survived – Greg Goode of Terre Haute, who did not draw a Trump-endorsed opponent.
This Is What Playing to Win Looks Like
The Republican Party spent decades asking itself the same question: do you fight or do you manage your decline gracefully?
The Tea Party answered it in 2010 – primarying RINO incumbents was the weapon that delivered Republicans 63 House seats and a decade of legislative dominance.
The key that helped lead to a host of conservative reforms in the state was by most accounts the Right to Work issues, which conservative advocates made a major issue in the 2010 primaries.
Right to Work laws strip union bosses of their ability to hold workers hostage at the threat of having them fired if they fail to fork over chunks of their paychecks to union bosses.
Without Right to Work, there's nothing stopping union bosses from extracting those forced union dues from workers – money which then becomes a huge source of funding for Democrat candidates.
The programs run by Right to Work advocates made huge gains in the 2010 Tea Party wave and as a result Indiana became the 23rd state with a right-to-work law in 2012.
With the supply lines running from captive workers’ pockets into Democrat candidates’ campaign war chests severed, it cleared the way for a host of conservative policy wins, including lower taxes and spending, school choice, and pro-Life protections for the unborn.
But winning often breads complacency,
And politicians who think voters won’t hold them accountable tend to go bad – or at least weak in the knees quickly.
Worse, when a big enough portion of the Republican base starts only paying attention in November, then wolves in sheep's clothing can creep in.
All of that can be even more of a problem when party leadership is firmly in the hands of a dominant national figure.
That is unless that singular leader is committed to enforce the lesson nationwide.
And it takes repeated discipline.
In the wake of the Tea Party wins, establishment RINOs in Indiana thought they could go back to business as usual. Mitch Daniels, the RINO Governor in office at the time, thought he could be president and thought opposing Right to Work would help him. Voters made clear that it would be the end of his political career if continued to stand in the way.
What happened in Indiana last night could signal the return to that kind of fighting spirit within the GOP to politics at every level, not just the presidential race.
Democrats need to flip four seats in November to take the gavel from Republicans. Every map matters. Every senator who decides his personal comfort is worth more than the House majority is a liability.
"There are consequences and accountability to those actions," said Marty Obst, the Republican consultant who led the Indiana redistricting push. He was right.
The senators who blocked this map had 21 different justifications. Their constituents opposed it. The tone was too aggressive. Indiana people don't like being told what to do. The national strategists don't understand barbecues and church fish fries.
Voters in their own districts heard all of that and chose the Trump candidate anyway – by double digits.
John Thune Is Watching
This is the part the national media will miss.
Indiana was proof of concept. Trump reached into a state primary with money and endorsements and removed people who defied him – regardless of how long they served or how many local endorsements they had collected.
Six veteran legislators found out last night that 20 years in the Indiana Senate means nothing if you vote against the base when it counts.
John Thune is the Senate Majority Leader. His job right now is keeping Republican senators in line on the budget, on spending, on every fight that determines whether Trump's second term produces results or gets strangled in the chamber.
Any senator thinking about going wobbly just watched six of their colleagues get fired by their own voters in a state Trump won by 20 points.
Indiana made the warning concrete. It is not atmospheric anymore.
