WASHINGTON (AP) — A string of unrelated events are highlighting divisions among Republicans just when they'd like to show a united front to exploit the White House's latest political problems.
Tensions between libertarian-leaning and more mainstream Republicans were on vivid display Tuesday.
Sens. Rand Paul and John McCain clashed over Apple Inc.'s tax-avoidance strategies.
Meanwhile, an immigration plan that's backed by the White House and many establishment Republicans appears closer to a showdown with wary House conservatives.
And Oklahoma's deadly tornado threatened to reopen a painful intra-GOP debate over the wisdom of borrowing money to help storm victims.
All political parties have their divisions, of course. It's possible the controversies dogging the White House will play a much bigger role in next year's elections than will these Republican disagreements.
