I've been following McCain since the early phase of the primary. And let me tell you; it's IMPOSSIBLE to keep up with him.
There's just too much going on/wrong with this guy. There's just too much crap like
flip-flops
reverse flip-flops
Russian mob ties (and you though Rezco was bad)
the lobbyists
the fundraisers
the canceled fundraising events (rofl)
the racism (ask the Arizona Indians and the Katrina Survivors)
the misogyny
his first wife
his current wife
his treatment of both of them
his lobbyist mistress (Iseman) (the NYT can backtrack all they want; McCain's 'assistance' is evidence enough of an affair)
his other affair (the daily kos has something they're saving for October)
his war record
his pre-pow record
his post-pow record
his treatment of POW widows-family members
the fights with constituents
the fights with fellow Congressmen (Strom Thurmond)
the fights with diplomats and guerrillas (whose bright idea was it to send McTemper on a diplomatic mission?)
the fights with Bush
the fights against Bush
the fights about Bush (I know, I know)
the age thing
the mental awareness thing (because, you know, he's not doing himself any favors)
the...you get the idea.

There are many websites out there dedicated to tracking this guy so you don't have to. You can come to them.
Here's a quick review so you'll know what to expect and what their 'target audience' is.

http://truth-about-mccain.blogspot.com / (A blog that covers McCain's early and recent foulups. Cunt-gate and the mobster thing is covered here. Written by a Black American, so you'll get to see what Black Americans generally think about him) Updated at least once a week, sometimes more often, with videos from blogsites. Provides context and perspective.

http://www.oldmanmccain.com / (A blog that covers every minor and major breaking screwup of McCain's. Updated daily, <b>McCain screws up daily</b>. Yes, <b>daily</b>. That's how low it's gotten. With videos and context and links to other anti-McCain sites.)

http://www.thingsyoungerthanmccain.com / (a blog specialized in things younger than McCain as well as things related specifically to age or interpretation of age. Updated a few times a week. With videos, links, some context.

http://mymccainblog.com / (a pro-mccain blog. Notice the lack of any coverage regarding McCain flip flops and such. A good place to get video clips about McCain as well, if you want to mix and match videos)

http://mccain.bravenewfilms.org / (the Brave New Films site which produces those lovely ads that the McCain campaign absolutely hates)

Feel free to add any relevant sites you like to read that follow the mccain campaign, to this thread.
