Mitt Romney is waking up to the fact that his highly negative, in some cases vicious, campaign against Newt and Rick will create problems down the road, should Mitt win the nomination.

So Romney’s senior advisors are putting together an outreach strategy:

Mitt Romney, mired in a frustrating slog toward the presidential nomination, has directed his top advisers to launch a multi-pronged effort to unite the Republican Party as the primaries draw to a close.

While Romney’s public activities are geared almost entirely toward winning the nomination, his campaign is on a private mission aimed beyond spring. Senior aides and surrogates — hoping to seize a moment when even some unfriendly Republicans are beginning to see Romney as inevitable — have spent the past several weeks making calls and visits to conservative leaders and activists who have resisted Romney’s candidacy.

In case you’re wondering.  No, I have not received a call.  I never do.
