That was fast.
Hours after Sarah Palin announced a "national tour" that will point her towards still to-be-announced destinations in New England, several other Republican presidential hopefuls revealed plans for making their intentions known:
Rep. Michele Bachmann, R-Minn., told Iowa reporters in an evening conference call that she'll be making an announcement, sometime next month, in Waterloo -- the Iowa town where she was born;
Presumed Republican 2012 front runner Mitt Romney let it be known that his long-awaited official announcement will take place on June 2 in New Hampshire;
Former Sen. Rick Santorum has also set his announcement date for June 6.
As for Palin, her own presidential intentions remain uncertain. But she certainly has had impact on her potential rivals.
