Is there some reason you can't donat eto political candidates (Obama, Clinton) using PayPal? Also, when did the max contribution go from $2,000 to $2,300? Did McCain-Feingold index the cap to inflation? And why is the Clinton campaign asking for contributions of up to $4,600? I understand you can de facto double the limit by donating once for the primary and once for the general election, but this seems different.
