Republican presidential candidate John McCain decided on a running mate early Thursday,” the AP’s Liz Sidoti reported a little while ago, “and one top prospect, Minnesota Gov. Tim Pawlenty, abruptly canceled numerous public appearances. Without explanation, Pawlenty called off an Associated Press interview at the last minute, as well as other media interviews in Denver, site of the Democratic National Convention. The Arizona senator will appear with his No. 2 at an Ohio rally on Friday.”
