Senators Mitch McConnell (R-KY) and John Cornyn (R-TX) — the top two Republican leaders in the U.S. Senate — announced yesterday that they will support “cloture” on the government funding bill, giving Harry Reid and the Democrats a procedural green light to fund Obamacare with only 50 votes. […] We knew Mitch McConnell and John Cornyn weren’t with us when they voted to fund Obamacare earlier this year. But then, under pressure from grassroots, they said they supported the effort to defund it. They even ran political ads in their home states to make voters think they were on their side.
But now, faced with the prospect of having to fight for the things they claim to believe, these Senate leaders have surrendered.
Mitch McConnell and John Cornyn have surrendered to Barack Obama, Harry Reid, and the Democrats. More importantly, they have surrendered to Obamacare — the biggest job killer in America. (link to do something about it)
It’s not an official Senate filibuster, because Harry Reid is using a procedural rules trick to strip the Obamacare defunding segment from the House Bill.    Ted Cruz is vowing to speak as long as possible to stop the “cloture” vote.
The “Cloture Vote”, is a pre-vote of sorts to enable Harry Reid to remove the Obamacare aspect with a simple 51 votes – Which Harry Reid has with Democrats alone.
Therefore anyone who votes for cloture is actually voting to support the Harry Reid process, and voting to support, ie. fund,  Obamacare.
This is where the Decepticons in the Republican ranks will show their manipulative faces.   They will vote for “cloture”, which relies on Republican support because the threshold is 61 votes affirming, then turn around and vote against the bill’s passage because their votes are not needed because the threshold drops to 51 votes (a simple majority) to pass.
So the Decepticons like Mitch McConnell will vote for cloture, then vote against the bill, and return to their campaign base claiming they voted against the bill.    The truth is they voted to support the bill, then voted against it only because after cloture it will pass without their support.
If Republicans really did not want to fund Obamacare they would not vote for cloture of the bill.
Mark Levin explains it better than me.
