Campaign finance rules already require sitting office holders to reimburse the government for transportation and security detail for political events. This applies to the president and congressional leaders, who also have access to government provided air planes. As for the quote, it's a bit ridiculous, because while high-minded, we obviously cannot operate according to that statement in a pluralistic society. We all abhor certain government programs, but the social covenant says we don't get to pick and choose. We're all in it together, whether we like it or not.
Yeah, if you think the current President, and the ones before him, are paying all the costs, I have some ice stands in the Sahara that I'll sell you! I don't think there should be ANY fundraising paid for by the general taxpayer; let the party organizations pay for it. I don't think the DNC or RNC (or any other established party organization) is paying the whole cost. If you have proof of that, I'd like to see it (and would stand corrected). I also think we, the taxpayers PAY the President and his staff to WORK on issues, not fly around the country and fundraise! These days they seem to spend at least a third of their time "fundraising' instead of solving problems; even with technology, which I use extensively, it doesn't take the place of the situation room and meeting with Congress.
