What Does This Paragraph Mean?

From a Collins press release:

One issue Senator Collins has raised it [sic] that the Administration's complex legal brief filed earlier this year calls for the invalidation of California's ban on same-sex marriages. It would have implications for several other states, but the brief curiously does not challenge the prohibition on same-sex marriages in some 30 states that do not recognize domestic partnerships.

Set aside the obvious distinction between supporting same-sex marriage and believing that banning such marriages is unconstitutional.

The real question is: What exactly is Collins driving at here? Is the subtext supposed to be that President Obama is "soft" on gay marriage, too?
