Mitt Romney and his supporters, who for months maintained that his business experience makes him the best presidential candidate in a stagnant economy, have subtly shifted emphasis to a different argument: that he would be a far better general election candidate than Rick Perry, the brash-talking Texas governor.In a bid to stymie Perry, who quickly overtook Romney as the Republican front-runner in national polls, the former Massachusetts governor is trying to cast his rival as too far out of the mainstream to defeat President Obama.
