Illinois Will Be the Key for Romney

While both CNN and the AP are still estimating that Mitt has twice as many delegates as either Santorum or Gingrich, he clearly lost momentum tonight.

While the Deep South was clearly not his home turf, Illinois, particularly in the Chicago suburbs, has the kind of upper class white collar Republicans where he thrives.

Romney remains the leader in delegates….But if Santorum can pull the upset in Illinois, Mitt would be in deep doo-d00 (to borrow a phrase from the first George Bush).

Watch the “Collar Counties” that ring Chicago.  They hold the key to the middle third of this Republican race.
