In that sentence Clinton don't propose rigging Palestine election, but instead she says that USA did mistake in supporting Palestinian election especially when taking consideration fact that parties who oppose USA and its allies interests were the most popular ones. Meaning that Clinton thinks that USA made mistake in accidentally supporting its enemies and in that process undermining its allies.
What nice way of saying that democracy should only be supported when the people vote for the ones that i like.
Democracy is just way to give people express what direction they want their government to go, if said people are your enemies it isn't necessary best move to give them more power to oppose you and your allies more. And when you talk to said allies after you have given their enemies more power to oppose them bring up that you did it for principality to support democracy for all costs, especially when you are representative of nation with long history doing opposite isn't necessary best way to go about things. But of course who knows maybe things would be better if Clinton had just said "**** you" to Israelis and told them that they just need to suck it up that Palestinians voted know terrorists and Israel haters to represent them and nobody would use that against Clinton now.
What a nice way of saying that perhaps it wasn't the best idea or interest of the US to meddle in the affairs of the middle east.
