Sarah Palin hogged the headlines but it was still a good weekend for President Obama — because Sarah Palin hogged the headlines.
A poll taken late last week gave the hockey mom from Wasilla a five-point lead over the next most popular contender for the 2012 Republican nomination, Mitt Romney, a former Massachusetts Governor.
Her speech to the Tea Party Convention in Nashville was covered by every network and newspaper from the liberal “mainstream media” that the Tea Party movement affects to despise.
Her attack on Mr Obama’s record on national security was taken seriously by pundits who agree that terrorists do not deserve due process in American courts, and her support for radical conservative challengers in Republican primary elections will have sent shivers down many a spine in the party’s national leadership.
These factors alone would make Mrs Palin a substantial political figure but in addition she has a national following and name recognition that was earned during the 2008 presidential campaign.
Despite the best efforts of Tina Fey on Saturday Night Live she has also immunised herself against ridicule, at least for now.
A serious Palin run for the White House is now a very real possibility, not the fantasy of a disaffected minority.
That should please Mr Obama’s staff immensely because Mrs Palin represents nothing but trouble for the Republicans for two main reasons.
First, she has already shown how she can split the conservative vote and thereby lose seats to the Democrats by backing hard-right candidates over moderates favoured by the Republican high command.
It happened in upstate New York in November last year and could happen again if Marco Rubio, her favourite candidate, unseats Charlie Crist in a key Florida Senate race due later this year.
Second, no potential Republican presidential nominee, with the possible exception of Mike Huckabee — the guitar-playing Baptist pastor and former Governor of Arkansas — is guaranteed to send independent voters back to the Democrats more than Mrs Palin.
She is a staunch social as well as fiscal conservative but, more alarmingly for independents, she still lacks much of the basic knowledge of the world that they consider a prerequisite for competence.
She said yesterday: “I’m never going to pretend that I know more than the next person.”
There will always be a constituency for this sort of politician, but it will not be big enough to win the White House in 2012.
