Should voting age be raised to 22?

Really my only problem is with those who are in college full time. I just read an article about kids who attend college in swing states registering to vote there. This can impact the election greatly. Anyone who is in or has been to college lately knows how far left professors lean and how vocal they are about their views. I feel that college students are very impressionable and tend to believe everything that is told to them by professors. This is fine when the topic is the professor's field, but not for politics. The fact is students really don't know how to vote on real world issues. They look at things from an ideological standpoint instead of what really happens in the real world. If they are not working full time and don't know what it is like to be in the real world then how can they have the knowledge necessary to vote. Another problem is the hostility that these students normally show to Republicans. Democrats can campaign at any college without any worries. Republicans have to worry about being attacked if they step foot on a campus. The nature of a college campus leads to group mentality/mob thinking and this makes it dangerous for Republicans to campaign there. I guess I have just been listening to college kids responses to these debates on NPR too much. Their lack of practical knowledge is a little scary.
