Tell us more what you know about the (relatively) Romney supoortive areas and GOP/conservative voters in Frisco, man. Please?
One thing many people may be surprised of, is like elsewhere around the country, conservative or Republican positions on ballot initiatives and certain ideas outperform the Republican candidates carrying the label on the ballot. One may conclude that there are certain "turn offs" to the Republican brand, but not necessarily the conservative idea.
A good example of this would be Prop 8 - 2008's initiative protecting traditional marriage.
Yes on 8 received 25% of the vote in San Francisco, far outnumbering John McCain's 13% or so vote totals.

The precincts that voted in favor of Prop 8 were in Chinatown/North Beach, the Financial District and some parts of SOMA around Market St near Union Square, Bayview (Higher African-American population than the rest of the city), and a handful of precincts around the Sunset (heavily Asian) and Lake Merced.
As you can see, some of the precincts that voted No on 8 in the Sunset had a much higher percentage of "Yes" voters than the remainder of the city. Even the gay-dominated Castro district had precincts register atleast 3% of the vote in favor of traditional marriage.
This is a good map that is less about D vs R -- with the notable exception of Bayview with high black opposition to SSM at the time...but the average composition of conservative vs liberal position on an issue or a ballot initiative.
However, if you compare this particular map to Obama vs McCain, you can see that the conservative position on the given issue outperformed the Republican candidate.
As recently as Nov. 2012, there was an item on the ballot expressing opposition to corporate personhood. It passed 81%-18%, but the "No" had nearly 15,000 more votes than Mitt Romney did.
Even in this extreme liberal enclave, conservative *ideas* (Although still very unpopular in the city) outperform Republican candidates themselves.
