LINDA WERTHEIMER, HOST:
Mitt Romney has wrapped up his most extensive campaign trip since becoming the all-but-official Republican nominee for president. Over the past five days, he visited six potential battleground states, touring each by bus. Along the way, he honed his attacks on President Obama, while also trying to show voters a more relaxed Mitt Romney than they've seen so far.
The tour, called Every Town Counts, stayed mostly in counties friendly to Republicans, ending with three stops in Michigan yesterday, the state where Romney was born.
