After three more primary losses tonight (VA, MD and DC), Sen. Clinton seems to be forfeiting next week's Wisconsin primary and Hawaii's caucus to bet heavily on Texas and Ohio in three weeks. RI and VT are also scheduled for March 4th.
Tonight Clinton is already campaigning in Texas, trying to cement the lead that at one time looked insurmountable, but is now in play. Sen. Obama spoke tonight from Madison Wisconsin; and from all indications, he's continuing to take nothing for granted and is appearing in as many states as possible.
The strategy of ignoring the smaller states for a later, larger potential windfall is shaky at best. Rudy Giuliani took himself out of the running by waiting for Florida, and by doing so he had no momentum to carry into the state and he lost miserably.
Next week's Wisconsin and Hawaii contests will probably add to Obama's momentum. The only thing going for Hillary after next Tuesday is a two-week layoff before the TX and OH primaries. If she gels her base in those states and wins both of them decisively, there's a good possibility that she'll take the lead back. And more importantly, squelch Obama's momentum.
But giving up states is never a good idea, and by this time next week Obama might have ten states in a row he's won. And that might get enough of Hillary's base to switch to the "winner" that he'll prevail in those states.
One thing is sure; if Obama wins next week, and then defeats Clinton in TX and OH, there's no doubt that he'll be our nominee for president.
