Quite easily. I've been a union member for longer than I can remember, and I've seen about 400 picket lines in that time. Over that same period I've seen union leaders frog marched out of local union offices - and International buildings - owing to their violation of existing anti-corruption laws (laws which have existed since 1959). And, of course, I've seen prognosticators like you over that time as well, those who've "been on the front lines" and what not but who seemingly harbor more hatred for their union leaders than they do those who took their friggin' jobs.
It's people like you who enable bad union leaders. Why? Because I'm betting that my mention of Landrum-Griffin was the first time you've heard of it, something which betrays your overreadiness with the mouth as opposed to the action. If this "corruption" were so well-entrenched and so pervasive, are you telling me that none of your brothers and sisters - hell, YOU! - have contacted the DOL? If not, why? Don't do the easy thing, flying off at the mouth about "corruption" when you've done diddly-shit to combat it under the extremely-strong laws made to prevent/punish such behavior. That you've done nothing in that vein suggests you're full of shit about the level of corruption, especially given that - as an employee of the Change to Win Coalition and former AFL-CIO worker - I've never, not once, heard anything on the level you're suggesting regarding SAG. Go peddle that crap to someone dumb enough to buy it, my friend.
I've seen many union "members" like you in my time. Those who're quick with the criticism and charges, yet a bit slow on proof that such a situation even exists, never mind actually doing anything about it. What I suspect is that you're one of those free-riding union "members" - we call them Taft-Hartley members - whose anger at the union stems not from this mythical "corruption" you're alleging, but from your resentment over having to pay dues. If it were pure corruption, all you'd have to do is call the DOL (would you like their number?) and they'd be MORE than happy to help considering who's in charge over there.
As to the Iraq speech: No record, huh?

If you had you'd know that it's physical properties don't allow for permanent adhesion/cohesion, thus the need for repaving. It's not a "poor job" of repaving, it's simply physical limitations on asphalt. Damn man, learn about something for a change, especially prior to presuming to speak in public about it.
