The purple-tie (establishment) Republicans in Congress know it’s possible that they will lose their majority in the Senate (and see their majority reduced in the House) if they continue to block Trump’s agenda which is rooted in Tea Party philosophy, so whether they decide to cooperate between now and the 2018 midterms is what’s important, and if they don’t start cooperating soon, many of them up for reelection in 2018 will lose in the primaries to Tea Party types, thus ostensibly increasing the risk that the Democrats would win big in the general election, yet the Tea Party is what won for Trump and has won since 2010 when the Tea Party movement began.
