The Clinton campaign is touting a pair of Quinipiac polls showing her with commanding
leads in Ohio and Pennsylvania of 21 points and 16 points,
respectively. If she were to win those states by such margins, she
could be in a position to catch Obama in the delegate race. But
unfortunately for her, these contests are likely to tighten. For
one thing, the polling period ended on Feb. 12, before news hit of
Obama's stunning trio of victories in the Potomac primaries. For
another, Obama hasn't campaigned in either state yet. There are
almost three weeks between now and the Ohio primary, and more than
two months before Pennsylvania. That gives him plenty of time to
campaign there, spend money on ads, and ride his wave of momentum.
So Clinton still may win there, but she's unlikely to do so by wide
enough margins to erode Obama's delegate lead. It seems to me that
these polls represent a ceiling of support for her, while for him
they're only the floor.
