Is It Surprising that Dems Can't Filibuster Obamacare Repeal?

Karl Rove makes the case in the WSJ that the GOP can repeal Obamacare with just 51 votes and avoid a Democrat filibuster through the budget process of reconciliation.

Will this 51-vote strategy work? One long-time GOP budget whiz, embarrassed he hadn't thought of this, told me it would. Another Republican veteran of the budget wars agreed, though she had some concerns that certain elements of ObamaCare, such as some insurance provisions, might be beyond the reach of reconciliation.

Huh? Really? Republicans hadn't thought of this? This is how the whole freakin' Obamacare bill got passed in the first place! I like Karl Rove, but if he is really surprised about this revelation, then he's been out to lunch the past two years.
