Via Hot Air: Allahpundit independently makes the same suggestion...
If I were Crist, here’s what I’d do. First, I’d dial up Jeb Bush and ask him whether there’s any chance whatsoever that he’ll endorse me. If he says no (which seems likely), either because he’s backing Rubio or staying out of the race, then I’d dial up Rubio and offer him a deal. In return for me dropping out right now, endorsing him, and helping him fundraise, I’d ask for a commitment that he’ll help me beat Bill Nelson in 2012. That’s really the only way at this point that Crist can regain his standing among the base, whom he’ll need to have onboard for any shot at the Senate.
...that I did last month, only I didn't bother with suggesting that Crist give Jeb an opportunity to bail him out. It's not too late, Governor: you still have something to trade. We don't have to let this situation deteriorate further.
But the clock's ticking.
