The problem is that the GOP has 24 of the 36 Senate seats up for election in in 2016. The Dims only need to win 4 for a tie and 5 to take control of the Senate. Something like 8 of those seats are up in states that went for Obama both times.
The talk of blocking any Obama nominee is purely BS aimed at the base in the primaries and will be quickly forgotten once a nominee is in place. What I see playing out is come September the GOP will find that they are in real danger of losing their majority in the Senate because the Dims and the media have once again successfully depicted them as obstructionists placing party over country. In response the Senate concerned about keeping their jobs and holding on to the majority will approve Obama’s nominee....
When push comes to shove the GOP will find retaining their majority is far more important than the justice that replaces Scalia. It’s imperative that they hold the Senate to fight another day. As Scalia proves these 80 year old justices are not going to last forever and it the GOP wants to stop the left from packing the Court with liberals for decades to come they must retain control of the Senate to have any shot of stopping the left’s takeover of the Court in the next few years. IMHO maintaining control of the Senate is even more important than who is elected president. It’s time to start playing the long game instead of what is politically popular now..but I’m not hopeful.
Obama isn't on the ticket to bring out legions of nonthinking juniors and reflexively-racist DemonRat Plantation voters this time. Beastwoman is putting Democrat voters to sleep. The Bern will take the Young Communist League home with him when Hillary! takes the nom away from him.
The only player energizing Democrat voters is Donald Trump. He's calling them in with Left-themed attacks on Bush and Cruz that are right out of the 2004 Kerry campaign.
Those voters, if they come out in the general, will be the down-ballot threat to the GOP Senate that Hillary will not bring because she's so godawfully boring.
That could have been Slick Willie's motivation all along in encouraging Trump to jump into the GOP nomination race. (And I think he did.)
Whether they will choose to do so is the real question.
They did allow Obama to appoint Kagan and Sotomayor. They also allowed him to appoint Lynch.
So there is plenty of precedent, unfortunately, for them to do the wrong thing.
