I wrote a post...

...a week or so ago that asked the question, What if establishment Republicans just give up on the GOP and migrate to the Democratic Party?

In Joe Nocera's column in the Times today, he talks about the possibility that Kevin McCarthy (above), the new Republican majority leader, may not support reauthorization of the Export-Import Bank (my emphasis):

Business is now up in arms. On Monday, the Chamber of Commerce and the National Association of Manufacturers held a conference call to decry the threat to the Export-Import Bank and promised a “full-court press” to get Congress to take up the reauthorization.

So, again, I ask: If the Republican Party continues down its crazy path, what's to stop groups like the Chamber of Commerce, for example, from backing sympathetic Democrats?
