It appears in the music video, and judging by the high sound of the chord voicings,
that Garrett plays this with a capo way up the neck, but this is easy and in the same key,
so it's the version I worked out, and it sounds pretty much identical. 

I play the Eb as x6504. One thing you can do that sounds cool and makes it easy -
in the pre-chorus, play your D as x5403x, so you can easily slide between the C, D
and Eb chords.

[Verse 1]

G 
Here I go again
Bm
Liquored up and then
Em                  C             D
Singing Propagandhi until I lose oxygen
G
Probably want my tab
Bm
Problem that I have
Em                     C             D
But luckily for me all my bartender friends are rad
G
I know I wear my stress
Bm
I know you're not impressed
Em                             C            D
But you're not the reason that I put on my party dress
   G
To go out and have a few
Bm
And if you only knew
Em                          C                  D
That me leaving wasn't the worst thing I could do to you

[Pre-Chorus]

C
I'm not a Christian man
D         Eb        Em
I got no grandiose plan
          D               C
I'm just trying to stay alive
C                        D           Eb
With all my money spent paying this god damn rent
Em       D          C
And the tension is high
        D
Do you wonder why?

[Chorus]

G
Everybody dies
Bm
Everybody dies
Em              C            D         G
Everybody gets fucked every once in a while
G 
Everybody tries
Bm
Everybody lies
Em                        C          D             G
'Cause everybody kind of sucks deep down in their soul
G                  Bm
I guess heaven sent another president
Em                       C            D      G
But does it even really matter who it is anyway?
G
When everyone's afraid
Bm
No one's getting laid
Em                  C            D         G    Bm  
But everybody gets fucked every once in a while
Em              C            D         G    
Everybody gets fucked every once in a while

[Interlude]

G Bm Em C D

[Pre-Chorus]

C
I'm not a Christian man
D         Eb        Em
I got no grandiose plan

I'm just trying to stay alive
C                        D           Eb
With all my money spent paying this god damn rent
Em       D          C
And the tension is high
D
Do you ever stop and wonder why?

[Chorus]

G
Everybody dies

I guess heaven sent another president
Em                       C            D      G
But does it even really matter who it is anyway?

When everyone's afraid
Bm
No one's getting laid
Em                  C            D         G    Bm  
But everybody gets fucked every once in a while
Em              C            D         G    
Everybody gets fucked every once in a while
